Managing QoS

This chapter shows you how to configure and manage QoS Check Point Software Blade on a Security Gateway that provides policy-based traffic bandwidth management to prioritize business-critical traffic and guarantee bandwidth and control latency.. These procedures assume that you have opened SmartConsole Check Point GUI application used to manage a Check Point environment - configure Security Policies, configure devices, monitor products and events, install updates, and so on., as described in Opening the GUI Clients .

Defining QoS Global Properties

The QoS global properties include default values for QoS rule Set of traffic parameters and other conditions in a Rule Base (Security Policy) that cause specified actions to be taken for a communication session. parameters and unit of measure.

Configure QoS global properties in SmartConsole.

Note: You must close SmartDashboard Legacy Check Point GUI client used to create and manage the security settings in versions R77.30 and lower. In versions R80.X and higher is still used to configure specific legacy settings. before you can work with global properties.

To configure QoS Global Properties:

1. In SmartConsole click Application Menu > Global properties > QoS.

2. In the Global Properties window, configure these parameters:

   Weight:

   • Maximum weight of rule: The maximum weight that can be assigned to rules. The default value is 1000.

   • Default weight of rule: The weight to be assigned in the Action column by default to new rules, including new Default rules.

   Rate:

   • Unit of measure: The unit specified in QoS windows by default for transmission rates (for example, Bps - Bytes per second).

3. Click Set Default to save the default values.

Changing QoS Global Properties

To configure QoS Global Properties:

1. From the Policy menu, choose Global Properties or click the Edit Global Properties icon in the toolbar.

   The Global Properties window opens showing these fields:

   In the Weight area:

   • Maximum weight of rule: The maximum weight that can be assigned to rules. The default value is 1000, but can be changed to any number.

   • Default weight of rule: The weight to be assigned in the Action column by default to new rules, including new Default rules.

   • In the Rate area:

   • Unit of measure: The unit specified in QoS windows by default for transmission rates (for example, Bps - Bytes per second).

2. Click OK to save the changes to the QoS Global Properties.

Interface QoS Properties

You must first define the network objects, that is, the Security Gateway Dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources. and its interfaces on which QoS controls traffic flow.

After defining the interfaces you can specify the QoS properties for those interfaces. This is done in the QoS tab of the Interface Properties window. Defining the interface QoS properties involves setting the Inbound and Outbound active transmission rates and specifying the Differentiated Services (DiffServ) and Low Latency classes. You can change these definitions at any time.

Note - The QoS tab is only enabled for the interfaces of gateways that have QoS selected on the General Properties page of the Security Gateway.

Configuring Interface QoS Properties

To configure Security Gateway interfaces

1. Open SmartConsole.

2. Click Gateways & Servers and double-click the applicable Security Gateway object.

3. In the General Properties, click Network Management.

   The Check Point Gateway - Topology window opens.

4. If a list of interfaces does not show, click Get Interface.

   If you choose this method of configuring the Security Gateway, the topology fetched suggests the external interface of the Security Gateway based on the QoS Security Gateway routing table. You must make sure that this information is correct.

5. Double-click the appropriate interface.

6. In the Interface Properties window, click the QoS tab.

7. In the DiffServ and Low Latency classes area, you can specify the Differentiated Services (DiffServ) and Low Latency Queuing classes to be used on the interface.

   You can Add, Edit or Remove a class. Refer to Working with Differentiated Services (DiffServ) and Defining a Low Latency Class for more details on adding or editing DiffServ and Low Latency Classes.

   For information about DiffServ and Low Latency classes, see Differentiated Services (DiffServ) and Low Latency Queuing.

8. Click OK.

   Changes to the interface QoS properties are saved.

Do steps 4 - 7 for each applicable interface.

Working with QoS Policies

QoS policy is an ordered set of QoS rules in the Rule Base All rules configured in a given Security Policy. Synonym: Rulebase.. The Rule Base contains rules that you create, and a default rule. The default rule is automatically created with the Rule Base. It can be modified but cannot be deleted. The fundamental concept is that unless other rules apply, the default rule is applied to all data packets. The default rule is therefore always the last rule in the Rule Base.

The Rule Base specifies what actions are to be taken with the data packets. It specifies the source and destination of the communication, what services can be used, at what times, whether to log the connection and the logging level.

A QoS Rule Base is applied to specific gateways and interfaces. After you have created the Policy and defined its QoS rules you must install it on the relevant QoS gateways.

To Create New QoS Policy

1. On the gateway, make sure that the QoS blade is enabled.

2. In SmartConsole, from the File menu, select Manage Policies and Layers.

3. Click New.

4. In the Policy window, enter a Policy name.

   This name cannot:

   • Contain any reserved words or spaces.

   • Start with a number.

   • Contain any of the following characters: %, #, ', &, *, !, @, ?, <, >, /, \, :.

   • End with any of the following suffixes: .pf, .W.

5. Select QoS and then select a QoS Policy type:

   • Express - Quickly create basic QoS Policies

   • Recommended (default) - Create advanced Policies with the full set of QoS features

   Note: There are some limitations that can prevent you from enabling SecureXL Check Point product on a Security Gateway that accelerates IPv4 and IPv6 traffic that passes through a Security Gateway. or CoreXL Performance-enhancing technology for Security Gateways on multi-core processing platforms. Multiple Check Point Firewall instances are running in parallel on multiple CPU cores. with QoS Policies. For more, see: Acceleration Support for R77 Policies.

6. Click OK.

   The system saves the new Policy and SmartDashboard opens automatically. You can start to define your rules here.

Opening an Existing QoS Policy

To Open an Existing Policy:

1. In SmartConsole, click Security Policies Collection of rules that control network traffic and enforce organization guidelines for data protection and access to resources with packet inspection. > Manage Policies.

2. In the Manage Policies window, double-click a QoS Policy.

   SmartDashboard opens.

Creating New Rules

You work with rules in SmartDashboard. When you add rules, you can put the new rule anywhere in the Rule Base except after the last rule. The Default Rule must always be at the bottom of the Rule Base.

To add a rule	Select from Menu
After the last rule	Rules > Add Rule > Bottom
Before the first rule	Rules > Add Rule > Top
After the current rule	Rules > Add Rule > Below
Before the current rule	Rules > Add Rule > Above
To the current rule	Rules > Add Sub-Rule

To Delete a Rule

You can delete a rule using either the right-click menu of the selected rule or clicking the Delete button on the toolbar.

1. In the QoS tab, select the rule you want to delete.

2. Click Delete on the toolbar.

3. Click Yes to delete the selected rule.

3. The following properties are displayed for a QoS rule with a simple action type. You can change any of these fields:

   In the Action Type area:

   • Simple: The full set of actions with the exception of the Guarantee Allocation and the per connection limit features.

   • Advanced: The full set of actions with the Guarantee Allocation feature included.

   • In the VPN Traffic area:

   • Allow rule only to encrypted traffic: Check this box if you want the rule to be matched only by VPN traffic. If you do not check this field, rules will be matched by all traffic types, both VPN and non-VPN traffic. VPN traffic means traffic that is encrypted in this same Security Gateway by IPsec VPN Check Point Software Blade on a Security Gateway that provides a Site to Site VPN and Remote Access VPN access.. This field does not apply to traffic that was encrypted prior to arriving to this Security Gateway. This type of traffic can be matched using the "IPSec" service. For further explanation on how to use this check box for prioritizing VPN traffic over non-VPN, see Example of a Rule Matching VPN Traffic .

   • In the Action Properties area you can define the restrictions on bandwidth for connections to which the rule applies in the following fields:

   • Rule Weight: Enables you to define the weight of the rule. This field is checked by default and has the value defined in the Global Properties window in Defining QoS Global Properties. Leave this value as is to avoid a complete loss of bandwidth. For detailed information see Weight .

     Important - 0 rate in conjunction with 0 guarantee can lead to the rule's complete loss of bandwidth. To prevent this from happening, retain some ratio in the Rule Weight. The default is 10.

   • Rule Limit: Enables you to restrict the total bandwidth consumed by the rule. For detailed information see Limits .

     Note - When using weights or guarantees, the weighted fair queuing algorithm that QoS makes use of assures that no bandwidth is ever wasted. Spare bandwidth is divided among the backlogged rules. However, if you set a rule limit, it will not use spare bandwidth above this limit.

   • Rule Guarantee: Enables you to define the absolute bandwidth allocated to the rule. For detailed information see Guarantees .

     Note - The number you enter for the Rule Guarantee cannot be larger than the Rule Limit.

4. (Optional) The following additional properties are displayed for a QoS rule with an advanced action type. You can change any of these fields:

   In the Limit area:

   • Rule Limit: Enables you to restrict the total bandwidth consumed by the rule. For detailed information see Limits .

     Note - When using weights or guarantees, the weighted fair queuing algorithm that QoS makes use of assures that no bandwidth is ever wasted. Spare bandwidth is divided among the backlogged rules. However, if you set a rule limit, it will not use spare bandwidth above this limit.

   • Per connection limit: Enables you to set a rule limit per connection.

     Note - The number you enter for the Rule Guarantee cannot be larger than the Rule Limit.

   In the Guarantee Allocation area:

   • Guarantee: Enables you to allocate a minimum bandwidth to the connections matched with a rule. For detailed information see Guarantees .

   • Per rule: Enables you to define the absolute bandwidth allocated to the rule.

     Note - The number you enter for the Per rule cannot be larger than the Rule Limit.

   • Per connection: Enables you to manage the bandwidth at the connection-level.

   • Per connection guarantee: Enables you to restrict the absolute bandwidth allocated per connection.

   • Number of guaranteed connections: Enables you to allocate a minimum number of guaranteed connections.

     Note - The Number of guaranteed connections multiplied by the Per connection guarantee cannot be greater than the rule limit.

   • Accept additional connections: Check this option to allow connections without per connection guarantees to pass through this rule and receive any leftover bandwidth. Enter the maximum amount of bandwidth that is allowed for this option in the text box. This only occurs if all other conditions have been met.

     Note - Select a non-zero rule weight when Accept additional non-guaranteed connections is checked.

   • Outbound: Define the portion of the interface's outbound capacity to be reserved by defining a Constant Bit Rate and a Maximum Delay as described above.

   You must configure at least one of the two directional properties (Inbound / Outbound), and you can configure both.

7. Click OK.

Defining DiffServ Class Properties

To define DiffServ class properties:

1. In SmartDashboard, locate the relevant Security Gateway.

2. In the Gateway Properties window, click Network Management.

3. In the Interface window, click the QoS tab.

4. In the DiffServ and Low Latency classes section, click Add or Edit.

5. Click DiffServ Classes > Others.

6. Configure these properties:

   • Class: Select a DiffServ class from the list of defined classes.

   • Inbound:Define the portion of the interface's inbound capacity to be reserved.

   • Guaranteed bandwidth: The bandwidth guaranteed to be marked with the QoS Class.

   • Bandwidth Limit: The upper limit of the bandwidth to be marked with the QoS Class. Traffic in excess of the Bandwidth Limit: will not be marked. For example, if the interface's capacity is 256MB and Bandwidth Limit to 192MB, then traffic beyond 192MB will not be marked.

   • Outbound: Define the portion of the interface's outbound capacity to be marked by defining a Guaranteed Bandwidth and a Bandwidth Limit as described above.

7. Click OK.

Working with Low Latency Queuing

QoS Low Latency Queuing makes it possible to define special classes of service for "delay sensitive" applications like voice and video. Rules under these classes can be used together with other rules in the QoS Policy Rule Base. Low Latency classes require you to specify the maximal delay that is tolerated and a Constant Bit Rate. QoS then guarantees that traffic matching rules of this type are forwarded within the limits of the bounded delay.

For more, see: Low Latency Queuing .

Defining a Low Latency Class

To define a Low Latency class:

1. In SmartDashboard select Manage > QoS > QoS Classes.

2. In the QoS Classes window, click New > Low Latency Class of Service.

3. In the Class of Service Properties window, configure these class properties:

   • Name - The name of the Class of Service.

   • Comment -The text to be displayed when this class is selected in the QoS Classes window

   • Color - Select a color from the list.

   • Type - Select a type from the list.

4. Click OK.

Configuring an Interface for Low Latency

Use these procedures to configure interfaces to use a Low Latency or DiffServ Expedited Forwarding class.

To configure an interface for Low Latency:

1. Make sure that SmartDashboard is closed.

2. In SmartConsole, go to Gateways & Servers.

3. Double-click the applicable Security Gateway.

4. In the Check Point Gateway window, click Network Management.

5. Double-click the applicable interface.

6. In the Interface window, click the QoS tab.

7. Select Inbound Active and/or Outbound Active and set the Rate properties.

8. In the Diffserv and Low Latency classes section, click Add > Low Latency Classes.

9. In the Low Latency QoS window, select a class from the list.

10. Select Inbound Active and/or Outbound Active.

    Note: You must set at least one traffic direction to Active.

11. Configure these Low Latency properties:

    • Constant Bit Rate - The constant bit rate at which packets of this class will be transmitted.

    • Maximal Delay - The maximum delay allowed for packets of this class. Packets that exceed this value are dropped.

      Note: To configure an Expedited Forwarding interface to work as a DiffServ interface, set the Maximal Delay property to 99999.

Do these steps for each applicable interface on a Security Gateway.

Defining Low Latency Class Properties

To define Low Latency class properties:

1. In SmartDashboard, click a Gateways & Servers and double click the applicable Security Gateway.

2. In the Gateway window, click Network Management.

3. In the Interface window, click the QoS tab.

4. In the DiffServ and Low Latency classes section, click Add or Edit.

5. Click Low Latency.

6. Configure these properties:

   • Class: Select a Low Latency class from the list of defined classes.

   • Inbound:Define the portion of the interface's inbound capacity to be reserved.

   • Constant Bit Rate: The constant bit rate at which packets of this class will be transmitted.

   • Maximal Delay: The maximum delay that will be tolerated for packets of this class. Those packets that exceed this delay are dropped.

   • Outbound: Define the portion of the interface's outbound capacity to be reserved by defining a Constant Bit Rate and a Maximal Delay as described above.

   You must configure at least one of the two directional properties (Inbound / Outbound), and you can configure both.

7. Click OK.

Viewing QoS Security Gateway Status

To see the QoS Security Gateway status, click Security Gateway in the Gateways & Servers view in SmartConsole. The status information shows on the Summary tab at the bottom of the view.

Enabling Log Collection

In order for a connection to be logged, the QoS logging flag must be turned on and the connection's matching rule must be marked with either Log or Account in the Track field of the rule. For further information on how logging features work, see Overview of Logging .

To Turn on QoS Logging

A QoS Security Gateway logs to the log if Turn on QoS Logging is checked in the Additional Logging page (under Logs and Masters) of the Properties window. By default, QoS Logging is turned on.

Confirming a Rule is logged

1. In SmartDashboard, select the rule whose connection will be logged.

2. Confirm that either Log or Account appear in the Track field.
